The project AQUASMARTT (data acquisition with underwater and above-water sustainable wireless nodes for monitoring how climatic changes affects natural disasters and biodiversity) targets the design of a sustainable and affordable integrated above water and underwater sensor network infrastructure for monitoring coastal environments and studying climate changes and biodiversity. Its objectives are:
- design a hybrid underwater and above water network architecture that enables data retrieval from submerged and surface sensors;
- develop the first Italian low-cost and low-power sustainable acoustic modem that can be used in a dense sensor network;
- formulate pathloss and fading models for radio frequency signals used for underwater and above water transmissions and to cross the water to air boundary;
- release an open-source network simulator for integrated underwater and above water networks;
- develop a proof-of-concept prototype demonstrator of the network;
- disseminate the results to scientific community, stakeholders, and the public.
Research and development activities results will be shown in final prototype validation and testbed/field demonstrations, involving both vendors and operators.
AquaSmartt is part of Spoke 6 – Innovative Architectures and Extreme Environments
- Definition of a shallow water and deep water use case in the Venice lagoon, definition with stakeholders of sensors to be acquired, spatial and temporal granularity requirements of the measures. Definition of the overall system architecture.
- Development of a first acoustic modem prototype, test of innovative modulation and coding schemes, exploration of underwater MIMO transmissions, and integration of the modem with the complete protocol stack suite provided by the open-source DESERT Underwater Framework. Design of a fair anti-jamming routing protocol based on Q-Learning. Transmission adaptation based on channel quality.
- Study radio frequency propagation underwater, formulation and validation of a propagation model with tank and sea tests. Inclusion of the proposed model into the DESERT Underwater simulation and experimentation framework.
- Development of a floating sensor prototype to be used as testing platform for communication and data acquisition in coastal areas and lagoons.
- Low Power RF reaches a range of 2 meters in underwater communication links in rivers and lakes, while in the sea it reaches only a few centimeters: still, it can be used to transmit data from surface nodes to a destination gateways even in the case they are partially submersed (e.g., when the waves cover them partially).
- Age of Information must be taken into account when developing adaptation algorithm in underwater networks, due to the time variability of the acoustic channel.
